To all whom t may concern:

Be it known that I, EUGENE FULLER, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented Acertain new and useful Improvements in Bed-Bottoms, of which the following-is a speciiication.

My invention relates to bed bottoms or mattress frames and has for itsessential objects a uniformY tension throughout the fabric; the facilityof interaction of constituent units or -parts'of the fabric;adaptability to independent movement of various areas; flexibility andstrength; inexpensiveness of construction; adaptability for assemblageand disassemblage; and absence from the exposed fabric surface ofirregularities tending to tear or abrade clothing, cleaning cloths, orother material. To the above ends essentially my invention consists insuch parts and in such combinations of parts as fall within the scope ofthe appended claims. Y

In the accompanying drawings which form a part of this specification Figure 1 is a top plan view of mattress frame or bed bottom embodying myinvention,

Figs. 2 and 3, side and end elevations respectively of the same,

Fig. 4, an enlarged bottom plan view of one of the fabric units showingportions of the connecting rods broken away,

Fig. 5, a section on line 5-5 of Fig. 4, and

Figs. 6 and 7, bottom plan views of the marginal and corner fabric unitsrespectively.

Like reference characters indicate like parts throughout the views.

The mattress or stretcher frame in the present instance comprises endbars 10 including flanges 11 and connected by side rails 12. The bedbottom or fabric comprises longitudinally disposed rods 15 ar ranged inrows. As illustrated, these rows comprise marginal or lateral rows 17,and intermediate rows 18. The number of rows is optional. The ends ofthe rods have enlarged portions or heads 20, preferably of curvedcontour, and vin this instance spherical in shape. Similar rods 22,having like heads 23, are arranged in rows transversely of the frame andfabric, and comprise marginal or end rows 25, and intermediate rows 26.

At the points of intersection of the intermediate rows are connectingunits or members represented in a general way by 28. In detail each unitcomprises a flattened hollow body 29 andi-four radial tubu' lar arms 30with retracted ends 31. The top wall'of each unit is closed, but thelower wall of the body is provided with a -central aperture or opening34 sufficiently large to admit insertion therethrough of any head 20 or23. Radiating from this aperture, in the arms 30, are slots 35 extendinginto the portions 31. The width of the slots 35 are throughout theirlengths greater than the diameters of the rods 15 and'22.. Therefore inassembling each head is inserted into the opening 34 simultaneously`with the insertion of its rod throughrthe slot 35, andthe rodis thendrawn radially until the head abuts against the seat or wall 31. Thehead is slidable in its tubular arm.

Upon the marginal rows 17 and 25, in-

termediate their ends are connecting units 37 similar to unit 28 exceptone radial arm 30 is omitted, as shown in Fig. 6. Y

Ait the intersections of the marginal rows are corner connecting units39 substantially like units 28 except that two adjacent arms 3() areomitted, as shown in Fig. 7, leaving but two radial arms.

rlhe bodies of the units 37 and 39 upon the end rows 25 have each spacedperforations 42 and 43 respectively, and the flange portions 11 of thebars 10 have series of perforations 45 spaced from each other greaterdistance than are those of the units 37 and 39. Pairs of supportinghelical springs 47 have hooks 48 on one end in perforations 43, andhooks 49 on their other ends in adjacent perforations 45. Pairs ofhelical springs 51 have one set of end hooks 52 in the perforations 42,and the set of end hooks 53 in perforations 45. 1t will be noted thateach of the pairs of springs 47 and 51 diverge from each other, and thatthe pairs 51 divergel at an equal angle from the rows 18. Thisarrangement of springs distributes the tension more effectively than ifthe springs were in alinement with the rows.

It will be observed that smooth movement is permitted between the rodsand units, and that the entire fabric may be manually and easilyassembled and disassembled. The upper faces of the units are smooth andunbroken.

I claim z* l. ln a bed bottom, the combination with a frame, of a bedfabric comprising rods provided with enlargements upon their endsarranged in longitudinal rows, rods pro-V vided with enlargements ontheir ends arranged in transverse rows, and connecting memberscomprising radial sockets engaging the enlargements and provided withVertical slots to loosely admit the rods, and means for connecting thefabric with the frame.

2. n a bed bottom, the combination with a frame, of a bed fabriccomprising rods provided with enlargements upon their ends arranged inlongitudinal rows, rods provided with enlargements upon their ends ar`ranged in transverse rows, and connecting members at the intersectionsof the rows comprising hollow bodies provided with central openings intheir bottom portions of greater size than the enlargements, and radialsockets on the bodies provided with slots of greater width than thediameters of the rods extending from the openings longitudinally andtransversely of the sockets, and means for connecting the fabric withthe frame.

8. ln a bed bottom, the combination of a frame, of a bed fabriccomprising rods provided with spherical enlargements on their ends andarranged in rows, rods provided Y with spherical enlargements upon theirends arranged in rows intersecting the first rows, members at theintersections of the rows comprising radial sockets adapted to receivethe enlargements and provided with oblong slots adapted to receive therods, and means for connecting the fabric with the frame.

4. In a bed bottom, the combination of a frame, a fabric bed bodycomprising rods provided with enlargements upon their ends and arrangedin rows extending longitudinally of the body, rods provided with-enlargements upon their ends and arranged in rows extendingtransversely of the body, connecting members slidably engaging theenlargements at the intersection of the rows, and pairs of helicalsprings disposed at an angle to each other and to the rows having theirinner ends engaging the connectingmembers at the ends of thelongitudinal rows, and having their outer ends engaging the frame.

ln testimony whereof l have aHiXed my signature.

EUGENE FULLER.
